The Arduino driver I linked was the only resource that had the implementation of the seesaw framework as well as the example code specific to this device: https://github.com/adafruit/Adafruit_Seesaw/tree/master/examples/Mini_I2C_Gamepad_QT On further thought, a link to the accompanying document from the manufacturer (https://cdn-learn.adafruit.com/downloads/pdf/gamepad-qt.pdf) might be more relevant for the binding which includes the hardware description as well as links to the above-mentioned Arduino driver. > >> + >> +properties: >> + compatible: >> + const: adafruit,seesaw-gamepad >> + >> + reg: >> + maxItems: 1 >> + >> + interrupts: >> + maxItems: 1 >> + description: >> + The gamepad's IRQ pin triggers a rising edge if interrupts are enabled. >> + >> +required: >> + - compatible >> + - reg >> + >> +additionalProperties: false >> + >> +examples: >> + - | >> + i2c { >> + #address-cells = <1>; >> + #size-cells = <0>; >> + >> + joystick@50 { >> + compatible = "adafruit,seesaw-gamepad"; >> + reg = <0x50>; >> + }; >> + }; >> -- >> 2.42.0 >> Thanks for the review.
